You forget to connect something.
Could be a simple as the ECM ground loose ground connection .
Maybe you caused a fusible link or fuse to open..
Battery dead ??
Could be any or all of these things

I went back through everything.
fusses are all good
relays are all good
when I turn on the key I don't get any computer response (ie no engine light on the dash)
the starter circuit is hot leaving the switch but then goes to the ECM and I lose it there.
I can't tell that I touched anything that would create this problem.
This is the 4th time I have done this job on this truck so I'm not new to it.
never had any problem before.
